I closed the hot water valve under my bathroom sink and reopened it last night, and since then I'm seeing a strange problem. If I barely turn on the faucet on hot I get water flow, but if I open the faucet more the water stops (and I hear what sounds like some shaking in the line under the sink).
I closed the valve again, unhooked the water line from the faucet, and opened the valve with the water line running into a bucket - nothing came out at all. I reconnected the line to the faucet and as before, I could get water flowing as long as I kept the faucet barely open.
Any thoughts on what it could be? I read about floodsafe hoses and thought it could be something like that, but the water line appears to be simple rubber. Could there be an auto shutoff valve somewhere that is preventing hot water flow when there isn't enough resistance?
